## Abstract

A universal submersible LED lamp/luminaire adapted to be placed inside a tube embedded in walls or floors of swimming pools, tubs, jacuzzies, or other bodies of water includes a hermetically coupled tubular casing defining posterior and anterior ends. The posterior end includes a connector, configured with an arrangement of five round pins for four connection configurations. The anterior end comprises a waterproof sealed lens and internally houses a panel of LEDs. An LED lighting control electronic board is housed inside the casing and is connected to the connector and LEDs. The board integrates microchips programmed to execute a pattern and sequence automated switching on of the LEDs and that are activated depending on the connection position of a power supply cable in connector.

## Claims

### Claim 1

A universal submersible LED lamp/luminaire adapted to be placed inside a tube embedded in the walls or floor of a swimming pool, tubs, jacuzzi or other bodies of water, the lamp/luminaire comprising:
a hermetically coupled tubular casing that defines a rear end and an front end, wherein the rear end comprises a waterproof power supply socket or female connector configured with an arrangement of five round pins for four connection configurations, and wherein the front end comprises a lens
a panel of a plurality of LEDs housed inside the front end; and
a LED lighting control electronic board housed inside said tubular casing and electrically connected to the waterproof power supply socket or female connector and to the plurality of LEDs, wherein the LED lighting control electronic board integrates a plurality of microchips, each microchip programmed and configured to execute and control a pattern and sequence of automated switching with respect to the plurality of LEDs that are activated depending on the connection position of a connector of a power supply cable in the waterproof power supply socket or female connector.

### Claim 2 (depends on 1)

The universal submersible LED lamp/luminaire according to claim 1,
wherein said tubular casing has an outer cable at both ends, the rear end being adapted to threadedly receive a rear tubular cover at a joint of which is arranged a waterproof seal element,
wherein the rear cover comprises a central hole with an interior cable configured to receive the waterproof power supply socket or female connector in a threaded manner with a waterproof seal,
wherein the tubular casing has an internal annular edge close to its the front end configured to receive and support a heat sink housed in the front end and on which the panel with the plurality of LEDs is fixed with a fixing means,
wherein the lens is arranged on a contour of the front end of the tubular casing and is held by a flange with waterproof sealing elements, wherein the flange includes an inner cable and is screwed onto the front end of said tubular casing in whose joint a sealing element is arranged as a waterproof seal.

### Claim 3 (depends on 2)

The universal submersible LED lamp/luminaire according to claim 2, wherein said flange comprises a protruding annular edge and presents an external cable configured to be screwed into another casing or other fixing means.

### Claim 4 (depends on 1)

The universal submersible LED lamp/luminaire according to claim 1, wherein said waterproof power supply socket or female connector comprises a perimeter surface in which there are four different indicators that refer to the different operation programs and lighting of the plurality of LEDs, wherein the connection of the power supply cable connector in one position or another executes and controls an automated lighting pattern and sequence of the plurality of LEDs.

### Claim 5 (depends on 1)

The universal submersible LED lamp/luminaire according to claim 1, wherein said waterproof power supply socket or female connector comprises an external cable configured to threadedly receive a waterproof hood mounted on the power cable connector power feed.

### Claim 6 (depends on 1)

The universal submersible LED lamp/luminaire according to claim 1, wherein a heat sink is in physical contact with an internal wall of said tubular casing to favor heat dissipation.

### Claim 7 (depends on 1)

The universal submersible LED lamp/luminaire according to claim 1, wherein the tubular casing has an internal annular edge close to the front end configured to receive and support a heat sink housed in the front end and on which the panel with the plurality of LEDs is fixed with a fixing means, wherein the lens is arranged on a contour of the front end of the tubular casing and is held by a flange with waterproof sealing elements, wherein the flange includes an inner cable and is screwed onto the front end of said tubular casing, and wherein a sealing element is arranged within a joint between the front end and the flange to provide a waterproof seal.

### Claim 8 (depends on 7)

The universal submersible LED lamp/luminaire according to claim 7, wherein the heat sink is in physical contact with an internal wall of said tubular casing to favor heat dissipation.

### Claim 9 (depends on 1)

The universal submersible LED lamp/luminaire according to claim 1, wherein the rear end is adapted to threadedly receive a rear tubular cover at a joint of which is arranged a waterproof seal element, and wherein the rear cover comprises a central hole with an interior cable configured to receive the waterproof power supply socket or female connector in a threaded manner.
